Title: Manufacture of semiconductor device
Inventor: KASAGI YASUO
IPC: H01L21/302
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To stably flatten an interlayer insulating film without optimizing etching conditions taking the rugged pattern of a ground film into consideration. SOLUTION: A resist 14 is applied onto a silicon oxide film 13, and the resist 14 is etched back until the silicon oxide film 13 is exposed. Then, the silicon oxide film 13 is wet-etched using the residual resist 14 as a mask until the silicon oxide film 13 is flattened. Thereafter, the resist 14 is removed. Therefore, the resist 14 and the silicon oxide film 13 are not required to be coincident with each other in the etching rate, and etching conditions are not required to be optimized taking the rugged pattern of a ground aluminum wiring 12 into consideration.

IPC: B23Q15/013
Filed: 1988-11-16
Abstract: PURPOSE:To attain the highly accurate positioning by comparing a position deviation value with the upper lower limit values of a settling range and deciding that the work is positioned for a prescribed period or above in the settling range from the signal level. CONSTITUTION:The command of a target position issued from a position com mand preparing part 21 is sent to a position command preparing part 22, and a position command Xd is sent to a deviation device 23. A present position P of a work 6 from a position detector 7 is also inputted to the deviation device 23 and the position deviation with the position command Xd is sent to a compar ing circuit 24. A comparing circuit 24 receives the target position Xd from the position command preparing part 21, prepares a settling range with the target position Xd as a central value, compares the upper lower limit value of the settling range with the position deviation, and a settling deciding circuit 25 decides that the work 6 is positioned for a prescribed period or above in the settling range from the signal level of the comparing output from the com paring circuit 24. In such a way, even when the overshoot occurs at the positioning of the work, the settling is correctly decided and the positioning can be executed with high accuracy.

Title: Camera with stroboscope device
Inventor: YOSHIDA MAKOTO
IPC: G03B15/05
Filed: 1992-10-02
Abstract: PURPOSE:To prevent the occurrence of a red-eye when a stroboscope is used by setting a photographic image frame at a position where a center line in the width direction of the photographic image frame is separated from a stroboscope light emitting part against the center line in a film width direction as for a camera with a stroboscope device.

The center S in the width direction of the photographic image frame 16 is arranged lower than the center T in the width direction of the film 12 and trimming information 18 is recorded in an upper spacing. Consequently a lens is arranged to align the center with the center S of the photographic image frame 16. Therefore the distance between the line linking the center point of the photographic image frame 16 and the center of the lens and the stroboscope light emitting frame is made long, and the angle formed by the stroboscope light emitting frame and the eye of a man and a lens center when the man is photographed is made large, and stroboscope light that is made incident on the eye is reflected not to the lens but to other direction, so that the rate of occurrence of the red-eye is reduced when the stroboscope is used.

IPC: H01L27/06
Filed: 1992-10-28
Abstract: PURPOSE:To electrically insulate and separate P-type wells from a P-type semiconductor substrate by forming a second P- and N-type buried layers having the same impurity concentration and same shape in the depth direction as a first P- and N-type buried layers have between the wells and substrate. CONSTITUTION:In this circuit device, P-type buried layers 2 and N-type buried layers 3 are formed on a P-type silicon substrate 1 and elements are respectively formed in N-type epitaxial layers 6 grown on the layers 2 and 3. The N-type epitaxial layers 6 are grown by forming the P-type buried layers 2 on the inside of the N-type buried layers 3 of a vertical type PNP bipolar transistor and N-channel MOS transistor. Since the N-type buried layer 3 is provided below the P-type buried layer 2 of the N-channel MOS transistor in such a way, a back gate can be made to float from the substrate 1 without dropping the turning-on withstand voltage of the N-channel MOS transistor.

Title: X-ray foreign matter inspection apparatus
Inventor: SHIBATA KENJI
IPC: G01N23/18
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray foreign matter inspection apparatus, which can inspect a foreign matter without being influenced by the shape of an object to be inspected or the foreign matter. SOLUTION: Data of a solid shape of an object 10 to be inspected are obtained by a solid shape-measuring means 2. The amount of X rays passing the object to be inspected is obtained by an X-ray data-measuring means 4. A correlation of the solid shape data at the same level as the object to be inspected and X-ray data is operated by a correlation-operating means 41. If no foreign matter is present in the object to be inspected, the solid shape data and X-ray data have the correlation with respect to an outer shape, and, therefore, an operation result indicating the presence of the correlation is obtained from the correlation-operating means 41. If the object to be inspected includes a foreign matter, the solid shape data and X-ray data have the correlation of the outer shape, but do not have the correlation with respect to the foreign matter.  As a result, the correlation-operating means 41 outputs an operation result representing the absence of the correlation. The foreign matter in the object to be inspected is inspected in this manner.

At the time point when any resource is inputted, it is registered on this resource managing table and a system automatically sets a managing number (element ID). This acquired element ID is registered in the database constructed in a storage device while being related with the group and element section of each article number (S9). Next, the CPU registers the element ID in the database while relating the resource type (S11).

Inventor: OTA TAKASHI
IPC: G06F3/02
Filed: 1991-08-20
Abstract: PURPOSE:To display every data being inputted so as to be easily compared, collated, and confirmed, etc. CONSTITUTION:The whole sentence of a piece of data is set as one character string, and is screen-displayed adjacently to the extension of character string display just before input.
